Pinning the Headboard

The act of pressing your Airborne wings into the back of the headboard of a girls bed after hooking up with them. This is in case the “single girl” you went home with is married or has a boyfriend who is deployed. If they are married or have a boyfriend that is deployed, that service member, upon returning home, will check behind the headboard to see if she was banging Jody while they were gone. This will also tell the service member how many dudes she hooked up with.

“Bro, I think she was married, so after we hooked up, I pinned her headboard just to make sure.”
